Networks 192, 194 and 196 communicate information between tiers 102, 104, 106, and 108, and client equipment 110. Access network 192 communicates information between CF tier 102 and client equipment 110. Private network 194 communicates information between CF tier 102 and application tier 104, between application tier 104 and acquisition tier 106, and between acquisition tier 106 and CF tier 102. Public network 196 communicates information between application tier 104 and acquisition tier 106, between acquisition tier 106 and OM tier 108, and between OM tier 108 and application tier 104. Information is also communicated directly between CF tier 102 and application tier 104, as described below. The information communicated between tiers 102, 104, 106, and 108, and client equipment 110 includes encoded television programs, audio files, data files, commands, procedures, other information, or any combination thereof.

CF tier 102 communicates with multiple sets of client equipment 110 over a wide geographic area, such as a regional area, a metropolitan area, a viewing area, or any other suitable geographic area that is supported by access network 192. Client equipment 110 includes a modem 112, a set-top box 114, a display device 116, and a remote control 118. The set-top box 114 includes a digital video recorder (DVR) 120 and a control module 125. Modem 112 is coupled to access network 192, and translates information from a form suitable for transmission over access network 192 to a form suitable for use by set-top box 114, and vice versa. In a non-limiting example, modem 112 is coupled to access network 192 via fiber-optic cables, a digital subscriber line (DSL), another network fabric, or any combination thereof. In a particular embodiment, set-top box 114 includes a display interface module (not illustrated).

The information that CF tier 102 communicates to modem 112 is sent to set-top box 114, which processes the information into a form suitable for display by display device 116 or for recording by DVR 120. Set-top box 114 receives digitally encoded content from CF tier 102 for display on display device 116, or for recording by DVR 120. Set-top box 114 can also receive data from CF tier 102, and render or display the data on display device 116. Further, set-top box 114 can send data to CF tier 102. Such data can include service requests, or commands from the subscriber, received by set-top box 112 via remote control 118. For example, control module 125 can include a remote control interface module (not illustrated) for receiving inputs to set-top box 112 from remote control 118. In this way, the subscriber can request services or information or respond to a request for information from IPTV system 100. Control module 125 includes instructions that are executable by set-top box 114 to control the data flow between the subscriber and IPTV system 100. Control module 125 can include an IPTV software platform such as Microsoft® TV IPTV Edition.

Control module 125 can facilitate data communication between set-top box 114 and IPTV system 100. For example, control module 125 can include a procedure whereby set-top box 114 receives a request to record content on DVR 120, or sends a status to IPTV system 100 that the content has been recorded. Likewise, control module 125 can include a procedure whereby the subscriber can interact with IPTV system 100 to receive and execute a viewing preference that the subscriber has created in IPTV system 100. Such preferences can be created via remote control 118, or through a subscriber account that is accessible through public network 196, such as through a subscriber's personal computer 198. A non-limiting example of remote control 118 includes a hand-held controller device, a game controller device, a keyboard/mouse device, another control device, or any combination thereof.

CF tier 102 includes a client-facing tier (CFT) switch 130, a data server 132, a terminal server 134, and a video-on-demand (VOD) server 136. CFT switch 130 manages communication with client equipment 110 through access network 192 and with application tier 104 and acquisition tier 106 through private network 194. CFT switch 130 is coupled to data server 132 that stores data transmitted in response to subscriber requests. CFT switch 130 is also coupled to terminal server 134 that provides terminal devices, such as a game application server, or other devices with a common connection point to private network 194. CFT switch 130 is also coupled to VOD server 136.

Application tier 104 includes application tier (APP) switches 140 and 141, an application server 142, an operation systems and support/billing systems and support (OSS/BSS) server 144, a subscriber and system store 145, a domain controller 146, and a client gateway 147. APP switches 140 and 141 manage communication with CF tier 102 and acquisition tier 106 through private network 194. APP switch 141 also manages communication with acquisition tier 106 and OM tier 108 through public network 196. APP switch 140 is coupled to APP switch 141. APP switch 140 is also coupled to application server 142 and to OSS/BSS gateway 144. Application server 142 provides applications to set-top box 114 through a set-top box application 143, so that set-top box 114 can provide functions such as recording and displaying content, messaging, and processing of IPTV data and VOD material. OSS/BSS gateway 144 includes operation systems and support (OSS) data, and billing systems and support (BSS) data.

APP switch 141 is coupled to domain controller 146 and to subscriber and system store 145. Domain controller 146 provides web access, for example, to subscribers via public network 196. Subscriber and system store 145 includes account information that is associated with subscribers who access IPTV system 100 via private network 194 or public network 196. Application tier 104 also communicates data directly to CF tier 102 through client gateway 147. In this embodiment, client gateway 147 is coupled directly to CFT switch 130.

Client gateway 147 provides subscriber access to private network 194 and tiers coupled thereto. In particular, set-top box 114 accesses IPTV system 100 via access network 192 using information received from client gateway 147. Access network 192 provides security for private network 194. Client equipment 110 accesses client gateway 147 via access network 192, and client gateway 147 allows client equipment 110 to access private network 194 once client equipment 110 is authenticated or verified. Similarly, client gateway 147 prevents unauthorized client equipment (not illustrated), such as hacker computers or stolen set-top box devices, from accessing private network 194 by denying access to these devices beyond access network 192.

For example, when set-top box device 114 accesses IPTV system 100 via access network 192, client gateway 147 verifies subscriber information by communicating with subscriber and system store 145 via private network 194, APP switch 140, and APP switch 141. Further, client gateway 147 verifies billing information and status by communicating with OSS/BSS gateway 144 via private network 194 and APP switch 140. OSS/BSS gateway 144 transmits a query across APP switch 140, to APP switch 141, and APP switch 141 communicates the query across public network 196 to an OSS/BSS server 164 (described below). After the client gateway 147 confirms subscriber and/or billing information, client gateway 147 allows set-top box device 114 access to IPTV system 100 content and VOD server 136 content. If client gateway 147 cannot verify subscriber information for set-top box 114, such as when set-top box 114 is connected to a different twisted pair, or when set-top box 114 is stolen, client gateway 147 denies transmissions to and from set-top box device 114 beyond access network 192.

Domain controller 146 communicates with public network 196 via APP switch 141. Domain controller 146 includes a web portal that allows a subscriber to access IPTV system 100 using a personal computer 198. Domain controller 146 also communicates with a data network 172 that is connected to a wireless access point 174. Wireless access point 174 communicates with a subscriber's wireless device 176 to provide wireless access to IPTV system 100. A non-limiting example of a wireless device 176 includes a cellular telephone, a personal digital assistant, a mobile e-mail device, a portable digital video device, another wireless device, or any combination thereof. Wireless device 176 includes a display device 178 for displaying information from IPTV system 100. Display device 178 includes a text display, a picture display, a video display or any combination thereof.

Acquisition tier 106 includes an acquisition tier (AQT) switch 150, a live acquisition server 152, a broadcast service 154, a video-on-demand importer server 156, and an Internet radio importer server 158. AQT switch 150 manages communication with CF tier 104 and application tier 104 through private network 194, and with application tier 104 and OM tier 108 through public network 196. AQT switch 150 is coupled to live acquisition server 152, video-on-demand importer server 156, and Internet radio importer server 158. Live acquisition server 152 acquires television content from broadcast service 154. Live acquisition server 152 sends the television content to AQT switch 150 for transmission to CF tier 102 via private network 194. The television content is further encoded at data server 132, and sent to client equipment 110 via access network 192. Set-top box 114 receives the television content from modem 112, decodes the television content, and transmits the information to display device 116 according to commands from remote control device 120.

Additionally, VOD importer server 156 receives content from one or more video-on-demand sources that are outside IPTV system 100, such as movie studios and programmers of non-live content. VOD importer server 156 transmits the video-on-demand content to AQT switch 150, and AQT switch 150 communicates the material to CFT switch 130 via private network 194. The video-on-demand content is stored on VOD server 136. When a subscriber issues a request for VOD content to set-top box 114 through remote control 118, the request is transmitted over access network 192 to VOD server 136 via CFT switch 130. Upon receiving such a request, VOD server 136 retrieves the requested VOD content and transmits the content to set-top box or 114 across access network 192 via CFT switch 130. Also, Internet radio importer server 158 receives content from one or more Internet radio sources that are outside IPTV system 100. Internet radio importer server 158 transmits the Internet radio content to AQT switch 150, and AQT switch 150 communicates the material to CFT switch 130 via private network 194. The Internet radio content is accessed by a radio interface module 148, as described below.

OM tier 108 includes an OM tier (OMT) switch 160, a TV2 server 162, the OSS/BSS server 164, and a simple network management protocol (SNMP) monitor server 166. OMT switch 160 manages the communication between OM tier 108 and public network 196. OMT switch 160 is coupled to TV2 server 162, OSS/BSS server 164, and SNMP monitor server 166 that monitors network devices. TV2 server 162 receives television content from live acquisition server 152, or video-on-demand content from VOD importer server 156 through public network 196. The television and video-on-demand content is sent by TV2 server 162 to OMT switch 160 and forwarded to a subscriber of IPTV system 100 who accesses public network 196 through personal computer 198.

Set-top box application 143 includes a radio interface module 148.

FIG. 8 is a flow chart illustrating an embodiment of a method for implementing an interactive Internet radio application in an IPTV system. The method starts in block 802, where a set of search criteria is displayed. For example, a subscriber can view the list of search criteria on music channel welcome screen 200, including “Genre,” “Artist,” “Popular,” or “Favorites.” The subscriber selects search criteria in block 804. Thus, the subscriber can use remote control 118 to interact with radio interface module 148 to select one or more of the search criteria. A decision is made as to whether or not the genre selection was made in decision block 806. If not, the “NO” branch of decision block 806 is taken, and a decision is made as to whether or not the artist selection was made in decision block 808. If not, the “NO” branch of decision block 808 is taken, and a decision is made as to whether or not the popular stations selection was made in decision block 810. If not, the “NO” branch of decision block 810 is taken, and a decision is made as to whether or not the favorites selection was made in decision block 812. If not, the “NO” branch of decision block 812 is taken and processing ends in block 814.

If the genre selection was made, the “YES” branch of decision block 806 is taken and a genre is selected in block 816. For example, the subscriber can be directed to genre and artist screen 220 and use remote control 118 to select a genre from genre window 225. The selected genre is used to search for stations that play music in the selected genre in block 820. Thus radio interface module 148 can access an Internet music site to search for stations that play the selected genre of music. A list of stations that play the selected genre of music is displayed in block 822. Here radio interface module 148 can display station selection screen 240, including a list of Internet radio stations that play the selected genre on set-top box 114 for review by the subscriber. The subscriber selects a station from the list in block 824. Thus the subscriber can use remote control 118 to select a station to play from the list. The station is played in block 826, and processing ends in block 814. As such, radio interface module 148 can stream the selected radio station to set-top box 114.

If the artist selection was made, the “YES” branch of decision block 810 is taken and an artist name is entered in block 818. For example, the subscriber can be directed to genre and artist screen 220 and use remote control 118 to enter an artist in artist entry box 229. The entered artist name is used to search for stations that play music by the entered artist in block 820, and processing continues in block 822, as described above. If the popular stations selection was made, the “YES” branch of decision block 810 is taken, a list of stations that are popular is displayed in block 822, and processing continues in block 824, as described above. If the favorite stations selection was made, the “YES” branch of decision block 812 is taken, a list of the subscriber's favorite stations is displayed in block 822, and processing continues in block 824, as described above.
